Question

a sailboat is traveling north at 10 km/h relative to the water. the water is flowing north at 5km/hr what is the velocity of the boat relative to ground​

Answer 1

Answer:

15km/hr

Explanation:

10=Vb-Vr

Vb=10+5=15

Given Vr=5

Answer 2

The velocity of the boat relative to ground​ is 15 km/hr.

Explanation:

Let v is the velocity of the boat relative to ground​. A sailboat is traveling north at 10 km/h relative to the water and the water is flowing north at 5 km/hr. Such that,

$v_b$ is the velocity of the boat relative to the water

$v_r$ is the velocity of the water.

Since, they are in same direction. So,

$v=v_b+v_r\\\\v=10+5\\\\v=15\ km/hr$

So, the velocity of the boat relative to ground​ is 15 km/hr.
